EVB3 Click Parameters
The key contacts of electromechanical tonewheel organs tend to saw a little on the busbar,
thus introducing a short click sound. If any corrosion occurs to the key contacts or busbar,
this will increase the length, and level, of this click. This aspect of the B3’s design causes
irregular scratching noises (commonly referred to as key click) when striking and releasing
keys. Hammond fans like these clicking noises, as they introduce a transient, percussive
quality to the note.
The EVB3 allows you to adjust the volume and sound of the key click. The tonal color and
volume of clicks are altered randomly, and independently, from the click on and click off
(release) volume settings.
You can use the Click On and Click Off knobs (in the silver section above the Condition
parameters) to independently control the click volume for the beginning (Click On), and
release of the note (Click Off). The click off is quieter, even if both controls are set to the
same value, as this mirrors the behavior of the original instrument. See Using the EVB3
Global Tone Parameters for information on these controls.
Click parameters
Click Min/Max sliders: You can determine a range for click duration, which can vary
between a short “tick and a longer scratch.” A random click duration (that falls within
the defined range) is used as you play.
Use the Click Min parameter to define the minimum click duration.
Set the maximum click duration with Click Max.
Note: Even if both parameters have identical values, there is still a random variation in
sound. This variation makes some clicks seem shorter than the value set with Click Min.
Click Color slider: Sets the tonal color of the click. This acts as a global control for the
treble portion of the click sound, which overrides (but works alongside) the random
click color variations.
Velo to Click slider (Extended Parameters area): Sets the velocity sensitivity of the click
parameters. It is found in the Extended Parameters area (accessed by clicking the
disclosure triangle at the lower left of the EVB3 interface).
